Well, I was going to suggest the ubiquitous fiddle leaf fern, but looks like you have a cat, and they are toxic to cats. You might Google plants that are non-toxic to cats and see if anything grabs your interest. I think some palms may be ok with cats (and they can grow fairly large), or you might look for a contemporary plant stand and just sit a smaller plant on it -- maybe a giant tropical bromeliad or something along those lines. That said, if your cat is prone to pester plants, it's probably not a good idea to include one in your décor. (Definitely don't put a fake plant in this pretty space.)
